Abstract

The Middlebury College Observatory is equipped with a 0.41-m reflecting telescope and a CCD imaging camera. Among the observational programs we have undertaken is the photometric study of short-period variable stars, especially delta Sct variables. There are many short-period (P < 6h) variables with amplitudes of several hundredths of a magnitude or greater, which are ideal objects for study with CCDs on small telescopes, especially in educational settings.
